Abstract

The present standard model of cosmology states that the known particles carry only a tiny fraction of total mass and energy of the Universe. Rather, unknown dark matter and dark energy are the dominant contributions to the cosmic energy budget. We review the logic that leads to the postulated dark energy and present an alternative point of view, in which the puzzle may be solved by properly taking into account the influence of cosmic structures on global observables. We illustrate the effect of averaging on the measurement of the Hubble constant.

The dissociation energy of highly excited dimers is averaged over the regions of strictly bound, metastable and free states in the phase space. It is demonstrated that a substantial decrease of the effective dissociation energy can be expected for weakly bound dimers and conventional diatomics held
